Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Please refer to fig. 1, which is a schematic structural diagram of a preferred embodiment of a casement window hinge provided by the present invention.

The utility model provides a flat-open window hinge, is including fixing installed part 3 on the window frame and fixing the trailing arm 1 at the casement wall, installed part 3 is stock column structure, and installed part 3 links to each other with long connecting rod 2 through

third bracing piece

6, 6 both ends of third bracing piece are articulated with installed part 3 and long connecting rod 2 respectively, long connecting rod 2 through first bracing piece 4 with trailing arm 1 links to each other, 4 both ends of first bracing piece are articulated with long connecting rod 2 and trailing arm 1 respectively, it has second bracing piece 5 to articulate on the long connecting

rod
